Longevity session · D05
Post-Impact Gamma Rest
Moves from Alpha to Delta — 10 Hz easing to 1 Hz over 10 minutes.
Choose the full transition or begin at the advertised audio target. You can scrub and extend either path in the player.
Frequency journey
How the rhythmic pulse embedded in the sound changes from the opening moments to its destination.
The embedded pulse gradually slows from 10 Hz (Alpha) to 1 Hz (Delta), so its rhythmic emphasis becomes less rapid over the ramp. The authored target begins at 10 min and holds for 16 min.
Long-form restorative listening
The restrained movement is designed for low-demand listening where continuity matters more than stimulation.
Give the transition room
Low-demand routines, quiet breaks, and extended periods of unwinding. Start quietly and let the ramp unfold instead of judging the session in its first minute. The target then holds for 16 min by design. You can also start directly at the target, scrub the journey, or extend the hold in the player.
Signal, not a scan. The line shows the modulation rate generated in the audio. It is not an EEG reading and does not promise that brain activity will follow the curve. Listening responses vary.

Choose the spatial feel
This session starts in isochronic mode. You can change how the beat is delivered without changing the frequency journey, or add a Shepard-Risset carrier drift for a continuously falling timbre.
- Monaural
- Two tones summed before they reach you, so the beat exists in the air rather than being built in your head. Smoother and less percussive than isochronic, and it works on speakers.

How this one is built
Built around a 40 Hz gamma carrier structure with phase-amplitude coupling. The fastest modulation in the catalog, layered over a light noise bed.
Listen responsibly
Brainwavest is a wellness and relaxation tool, not a medical device. Session names and guidance describe design intent, not a promised physiological result. This session runs on a 110 Hz carrier, below what a phone or laptop speaker reproduces — use headphones or it will sound almost silent. Start quietly, and never use rhythmic audio while driving.
